Densi To Prompt 'A Lot Of Mistakes' On 'NCIS: LA', Eric Christian Olsen Talks Deeks/Kensi Relationship

After a season and a half of will-they-won't-they, Mr. Deeks (Eric Christian Olsen) and Mrs. Blye (Daniela Ruah) decided to up the ante and take their relationship to the next level. As hard as they may try, however, the partners won't be able to keep up their seemingly platonic workplace charade forever.

"I think eventually the team's going to have to know what's going on between Kensi and Deeks," Ruah explained to TV Guide. "I don't think it'll be a surprise for any one of the other characters, especially not Hetty. I think she could see it coming a mile away."

In the meantime however, the duo's relationship will only appear in bits and snatches for the audience.

"They have to keep it serious and professional at work," Ruah said. "There's not a great, if any, distinction in the scenes that we did prior to dating officially to post-dating officially. Their professionalism and their banter and their looks are pretty much similar or the same. It's just in these little wonderful tidbits that the writers drop for us, such as scenes where they find themselves alone or on a date or whatever it is."
